Must be my trusty and magical Logitech Wireless Desktop Keyboard. I have it since 2002 and still working perfectly. This keyboard has seen countless hours of playing, end-less posts and whatnot.

And now the explanation of why I haven't replaced it yet and why it is magical: I use it with 2700 mAh rechargeable batteries and believe it or not, we have replaced them only 3-4 times since 2002!!! It's no joke. A curiosity related to this is that I didn't replaced its batteries in more than 5 years, because I did the first (2003, replaced the factory=crappy batteries) and the last (last december) replacements, while my brother did one or two replacements in the middle, he doesn't clearly remember.

hmm, Ive had this 22" syncmaster for 2 years now, epic thing. HD TV and a monitor?! PS3 look flawless through it too.

My Q6600 - its roughly 6 months old but I love it. 4Ghz on air with room to possibly hit 4.5? On a late batch? <3

And my HX520W PSU. Damn corsair know what they are doing - tad older than my Q6600, and managed to cope with all my system specs, Q6600@ 3.8 and my 260 on ftw bios WITH a H20 Loop and extra fans - 500W they say? pfft, more like 650.

For me, it would have to be my old Sony VAIO laptop. A 1GHz PIII with 256MB of RAM, bought 8 years ago(2001 sometime). It still works for basic tasks like microsoft office and internet browsing. I have a PIII based Celeron desktop from the same time still kicking around also with 512MB of RAM in it. I've been real tempted to hook it back up and install vista on it.

i'd say my p2 940... at 3.8 and soon as my water comes 4.2 which i can bench and prime as long as it's 0c in my house, once i go on water it's gonna be there for quite some time.. it's got more then enough power to keep me going for a while longer.. also my 8800gts 512's.. purchased almost 2 years ago and togeter about as fast or a bit faster then a gtx 260... still plays every game at very playable rates with good iq.

In my PC it would be my psu - enermax galaxy 850 launch version, over 2 years old and still got plenty of headroom left. My monitor as well, acer ferrari F20A with the S-IPS panel, that's 3 years old now at 1680x1050 and still no dead pixels, only problem is it doesn't detect when the pc shuts down and thus never goes into standbye...

Best futureproof thing i have bought is my PDA - 4 year old HP IPAQ hx4700 - when i bought it i also bought a tomtom bluetooth gps receiver which also came with a sd card with the software on to run with the pda, perfect then and is still now.

Longest lasting vid card would either be the Radeon 9700 Pro or the 8800GTX. I haven't had the 8800GTX as long as I had the 9700 Pro yet. Though, honestly, I think lots of video cards from the past couple years will last for many years. Games aren't advancing in graphics much these days, partly because the consoles lock down the capabilities rather well unfortunately.

My 8800 Ultra, the 384bit front side bus is the secret weapon of this amazing graphics card. I have it about 2 years, and i play every game at high res ( expect for crysis ) with high framerate.
Im so proud of him, the best Nvidia GPU ever made (G80).
